The case for fencing remains intact
Creel et al. argue against the conservation effectiveness of fencing based on a population measure that ignores the importance of top predators to ecosystem processes. Their statistical analyses consider, first, only a subset of fenced reserves and, second, an incomplete examination of ‘costs per lion.’ Our original conclusions remain unaltered.
